Don't get me wrong, I am not saying kids are not capable of things. For a personal example, and please don't judge me harshly for this but, when I was like 10 or 11 I slept over our neighbor's a lot and this 20 something daughter of the house used to sleep with me. To be damn honest I was a horny kid from the beginning and even though I never "engaged" in any acts I was pretty darn curious. And so this one time in the middle of the night I started "exploring" her. Now that I look back on it, if I wasn't a kid, it was pretty much sexual assault all of it.
But here is my point. I DIDN'T KNOW WHAT THE HELL I WAS DOING. My instincts drove me but I had no idea what it all meant. I never even saw a naked lady let alone any porn at that time. But here I was "researching" the female specimen for god knows what reason. I didn't get far with her though and I don't really know what would have I done even if I did. I was pretty much like a dog chasing a car with no idea what to do with it if I ended up catching it. That is my point regarding Hana Cook's depiction of shota. Sure boys can do stuff at young age but they sure as hell don't understand how to wreck someone's mind. I mean a teenage might but a pubescent boy? At best you can be taught things about sex but breaking someone's mind is an art you can't teach that easily even to adults. You will need to be either a demon incarnate, have a pretty fucked up childhood upbringing or experience of age to spur that kind of mentality. This definitely can't be triggered by some bully taking away your key-chain that you bought from some shop.
Not to mention the depiction of mothers go out of the window too. They start off all loving in the beginning of the doujin and then basically turn to loathing their own children during the sex. How the heck does that work? She isn't even brainwashed. She just automatically goes from hugging their spawns to wanting to sacrifice them by the time the sex is over.
So either the mother was a lying psychopath who was pretty good at faking love or Hana dropped the ball with character development as everything felt like jumping. Ehh, I dunno if I just can't handle heavy NTR or the whole character development by Hana bothers me to the point that I dropped the comic midway.
